Title: Production of solvent for dye used for pressure sensitive paper
Inventor: HASEBE SHINJI
IPC: C10G67/04
Filed: 1988-11-30
Abstract: PURPOSE:To easily obtain a solvent for dye used for a pressure sensitive paper having an extremely high solubility to the dye and high quality by a method wherein a raw material anthracene oil free from crystal which has been subjected to specified rough distillation is subjected to extraction, and is then subjected to specified hydrogenation and specified precise distillation. CONSTITUTION:An anthracene oil freed from crystal and having a nitrogen concentration of about 7,000ppm is subjected to rough distillation in the temperature range of 290-360 deg.C, and is then subjected to extraction to have a nitrogen concentration of about 2,000ppm, followed by hydrogenation with a hydrogenation degree of 1-8 to obtain a hydrogenated product with a nitrogen concentration of 100-1,000ppm. The hydrogenated product is subjected to precise distillation in the temperature range of 250-350 deg.C to obtain a fraction with a nitrogen concentration of 10-100ppm. The rough distillation removes unnecessary fractions, and alleviate the load at the time of the hydrogenation. The extraction removes polar nitrogen compounds, whereas the hydrogenation removes hetero-atoms, and simultaneously achieves hydrogenation of nuclei, thereby increasing the fluidity of the product. By the precise distillation, it is possible to remove lighter fractions having strong odors and heavier fractions which would worsen the hue of the product, from the product.

Title: Structure of filter for removing gas
Inventor: ENDO NAOTOSHI
IPC: B01D46/52
Filed: 1995-11-21
Abstract: PURPOSE: To prevent the deterioration of the angular part in the first place of pleats on the inlet side and to eliminate dispersion in residual ion exchange capacity of the angular part of pleats on the outlet side by inserting a separator between the pleats on the inlet side and on the outlet side and covering the angular part of the pleats on the inlet side. CONSTITUTION: In the filter unit 10, nonwoven fabrics 11a-11d of ion exchange fibers are laminated, the laminate is pleated, and the side parts 14-16 in parallel with air flow S are connected in the angular parts 12, 13. The angular parts 12, 13 are heat-fused to eliminate the gap between the nonwoven fabrics, the end T is formed to have an acute angle, and inlet side pleats A and outlet side pleats B are formed. An outlet side separator of a punching metal is inserted into the pleats B. Air does not permeate from the end part so that no ion exchange action takes place. Since a turbulent flow is generated on the outlet side, a laminar film between the filter and the separator is eliminated, enabling uniform gas contact.

Title: Dry barrel polishing inorganic media
Inventor: IKEDA YASUSHI
IPC: B24B31/14
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To enable even rough finish polishing by dry barrel polishing by sintering a mixed material of argillaceous particulates, abrasive particles and aluminium hydroxide particulates as a small grain shape. SOLUTION: In dry barrel polishing inorganic media by sintering a mixed material of argillaceous particulates and abrasive particles as a binding material, aluminium hydroxide is added to and mixed in the mixed material. By the aluminium hydroxide, the media can be formed not only as a cutting quality maintenance preferential type and but also can be formed as a wear-tear restraint preferential type by adjusting its adding quantity, but when 5wt.% or more is contained, a shape of the media largely collapses by sintering, and since the media having a desired shape is hardly obtained, it is desirable that 5wt.% or less be contained for a general use.
